In the title complex, [Pd(N(3))(2)(C(10)H(9)N(3))], the Pd(II) ion is in a slightly distorted square-planar coordination environment. The ligator atoms comprise the two pyridine N atoms of the chelating di-2-pyridyl-amine (dpa) ligand and two N atoms from two azide anions. The dpa ligand coordinates the Pd atom in a boat conformation, the dihedral angle between the pyridine rings being 24.4 (1)°. The pyridine rings are somewhat inclined to the least-squares plane of the PdN(4) unit, making dihedral angles of 29.02 (9) and 26.47 (9)°. The azide ligands are slightly bent, with N-N-N angles of 173.0 (4) and 174.2 (4)°. In the crystal, mol-ecules are connected by N-H⋯N and C-H⋯N hydrogen bonds, forming chains along the c axis. When viewed down the b axis, successive chains are stacked in opposite directions. Intra-molecular C-H⋯N hydrogen bonds are also observed.
在标题配合物[Pd(N₃)₂(C₁₀H₉N₃)]中，Pd(II)离子处于略微扭曲的平面正方形配位环境中。配体原子包括螯合二 - 2 - 吡啶基胺（dpa）配体的两个吡啶N原子以及来自两个叠氮阴离子的两个N原子。dpa配体以船式构象配位Pd原子，吡啶环之间的二面角为24.4(1)°。吡啶环相对于PdN₄单元的最小二乘平面略有倾斜，二面角分别为29.02(9)°和26.47(9)°。叠氮配体略有弯曲，N - N - N角分别为173.0(4)°和174.2(4)°。在晶体中，分子通过N - H⋯N和C - H⋯N氢键相连，沿c轴形成链状结构。沿b轴观察时，连续的链以相反方向堆积。还观察到分子内的C - H⋯N氢键。
